To all wlwm 'it my concern:

Be it known thatL'JERoMn C. JosLIN, a citizen /of the UnitedI States, iesi'din at Keene,l in the countyA of Cheshire and tate of New Hampshire, have invented a new and useful Improvement in Flasks for j Building Cement lValls, of which the following is a specification.

My invention relates to flasks for, building cement walls and more p al't-iularly to flasks for building foundatiofpiers and l abut-ments, the object being to. provide al flask which can be raised after it has been filled with cement so as to form a continuous wall withoutremoving the mold.

Another object of my invention is to provide a flask with very novel means-legumi@ ing it after the concrete 'has cohgaled, that it can be readilyfilled again.

Another objectof my invention is to procan be swung outwardly when forming a battered or' ornamental wall s'o as to clear the figure work before the flask is raised.

Another object of my invention is to provide a flask which can be easily and quickly adjusted so as to mold any width wall.

A further object is to' provide very novel means for supporting and guiding the flask when 'being raised.

still further object of my invention is to provide a central core in connection with the flask so that hollow walls can be molded.

Wit-h these objects in view, the invention consists in the novel features of construehereinafter fully described andpointed'out in the claims.

In the drawings forming a part of tliif specification Figure l is a side view of m improved flask showing it arranged on 'th walls inposition to be filled. Fig. 2 is an end view of the flask, the endbeing partlyg.. broken away. Fig. 3 4is an end view of a guide-member adapted to be'secured to the side of the mold for holding it in a vertical position on the wafll. Fig. 4 is a section taken on the line 4;-4 of Fig. 2 showing a portion of the core. Fig. 5 is a perspective view of my improved ask one side and end being removed, and Fig 6 is a top plan View of a. flask to be used around angles in walls.

In the drawings A and B indicate the .sides which are provided with strap-'brackcts A B at their ends, in which the ends C are adapted to be secured, the sides being of any desirable length, land having spaced jaws iD and .E -secured on their outer faces which are provided with slotted upper ends which are pivotally and adjustably mounted on cross-bars F by bolts D', E', one end of the cross-bars being provided with spaced "openings F, in which the bolts D ar',

adapted to fit, so that the sides can be adjusted to mold any width wall/desired. The

jaws being held in a vertical position by Ttal -wall the sides will clear the figure work before the flask is raised, as it is only necessary to have the slides swung a slight disy tance to enable the slides to be drawn upwardly without any danger of injuring the face of the' wall, as will be hereinafter fully described.

Mounted on each of the cross-bars F are slotted blocks G and H, which are rovided.

with vertical threaded bores, in w ich are mounted turn-screws I and J provided with disks I J at their lower ends loosely mounted thereon and square upper ends forming Wrench-receiving heads so that they can be readily turned. Vertical square bores are formed in the blocks to the other side of the cross-bars, in which are slidably mounted pins K, L having langled ends which are secured in the blocks b set-screws, which engagethe pinsand ho d them in an adjusted position, as will be hereinafter described.

etched guide-members M are secured to the sides of the flask after it has reached a height above' the ground, which are adapted to engage the'sides of the molded wall land hold the flask securely thereon.

When it is desired to form a hollow wal? j yokes N are secured on the bars between the blocks, by set-screws N the lower ends of the yokes having the up er ends of screws O, pivotally mounted tween the same which carry the core P which is normally held midway between the walls of the flask and isprovided with notches in its lower edge, in which the anchor-irons Q lit, for securing the two walls together.

In Fig. 6 I have shown a flask especially constructed for moldinov angles in walls, the sides S being connected= to short pieces T by :mgled irons U, which are provided with! slots which lit over staples secured in the/ sides, and are secured in place by pins. It l olI course beingr understood that this only applies to the outside wall of the flask, the .inside walls being` secured to a piece V, by g angled irons W.

The operation is as follows-The sides and ends are placed in position, so as to inold;l any width wall desired, the pins are then shoved downwardly to hold the same in posi- 5' tion and the flask is lilled with cement and allowed to harden. The screws are then opf ereted the pins being first bit with a hammer l once or twice so as Vto loosen the saine as the screws are turned, the sides and ends will be raised until they reach the top of the! walls. The guide-members are then placed on the sides so as to hold the mold in posig tion, and the pins'are forced vdownwardly i until they engage the top of the wall which l supports the mold. The screws are then; turned so as to bring them up above the l plane of the top ofthe sides and the mold is then lled with cement, this being repeated j until the desired height of the wall is obtained. The operation for molding a hollow wall being the same, except that the core is placed between the walls. It will be seen that when it is desired to mold a Wall lwith an ornamental face, the sides of the flask can be swung outwardly suleiently by loosening the set-screw, so as to clear the figure work before the mold is raised.

Y Having thus fully described my invention, what I claim as new and desire to secure by In a flask of the kind described, the i combination with cross-bars, of jaws adjustably mounted on said cross-bars carrying sides, ends carried by said sides, depending guide-members carried by the sides, an means slidably mounted on the cross-bars for raising and supgorting said mold, for the purpose describe A JEROME C. JOSLIN.
